UPDATE: US Diplomats in Cuba Mysteriously Suffer Severe Hearing Loss; Investigators Suspect Covert Sonic Weapon Used

August 10, 2017

HAVANA, CUBA — The U.S. State Department recently expelled two Cuban diplomats in May, after several Americans at the US Embassy in Havana began suffering from unexplained medical symptoms late last year. According to a report from The Washington Post, a small number of Americans began reporting symptoms in the fall of 2016 and some of them were either removed from the embassy for further medical treatment in the US or were asked to leave by the State Department. 

According to State Department spokeswoman Heather Nauert, the investigation is ongoing into possible source or cause, which are still unknown. However, The Washington Post reports that US officials believe Cuba used a “covert sonic weapon” in what is being described by some as an “acoustic attack” on Americans at the Embassy in Havana.


Severe Hearing Loss Due to “Acoustic Attacks” on Diplomats


Symptoms were reportedly so severe for some of the US diplomats in Havana that they were forced to cancel their tours early and return to the United States. Sources report that after months of investigation, US officials concluded that the Americans stationed in Havana had been attacked with an “advanced sonic weapon that operated outside the range of audible sound and had been deployed either inside or outside their residences.”

In comments to the press, State Department spokeswoman Heather Nauert noted that the US had reminded the Cuban government that it is obligated under the Vienna Convention to offer protection to diplomats. 


The Cuban government has a responsibility and an obligation. That is part of the reason why this is such a major concern of ours, why we take this so seriously.” —State Department spokeswoman, Heather Nauert


According to officials, the FBI is currently conducting an investigation. While it is investigating Cuban responsibility for the attacks, investigators are also looking into the possibility that there could have been involvement of a third party, like Russia or China, operating in the country without the direct knowledge of the Cuban government.

The Cuban foreign ministry responded to the reports stating that it would “never, nor would it ever, allow that the Cuban territory be used for any action against accredited diplomatic agents or their families”. The Cuban government says it launched an investigation into the incidents when it became aware in February of this year.

Further US actions against Cuba are expected, if the investigation points to the Cuban government specifically targeting US employees and citizens for such attacks.

  1. We don’t yet know the cause of complaints in this case of American and Canadian diplomats in Cuba, but Bob Dobie and anyone else who thinks this story is “fake news” should look carefully at the history of noise-induced Sick Building Syndrome, industrial wind turbines, and torture. In each of these areas, infrasound has been shown to be associated with symptoms similar to those experienced by the affected diplomats. In general, these symptoms include a variety of health complaints, such as headaches, migraines, dizziness, motion sickness, tinnitus, sleep disturbance, memory and concentration difficulties, and unpleasant ear and other bodily sensations. Although ultrasound and microwaves are being floated in the media as alternate theories of the cause of the complaints, infrasound seems to be the most likely cause. With regard to wind turbines, with which I’m somewhat familiar, I should state that I know of no association between acoustic emissions from wind turbines and hearing loss, but it is quite conceivable that extremely high levels of infrasound could be destructive to hearing. Until we know more, we should keep our minds open to a number of possibilities and not treat this story as fake news.
